+# Yuyuan-3.5B model (chinese)，one model of [Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM).
+As we all know, the single direction language model based on decoder structure has strong generation ability, such as GPT model. **The 3.5 billion parameter Wenzhong-3.5B large model, using 100G chinese common data, 32 A100 training for 28 hours,** is the largest open source **GPT2 large model of chinese**. **Our model performs well in Chinese continuation generation.**
+
+## Usage
+```python
+from transformers import pipeline, set_seed
+
+set_seed(55)
+
+generator = pipeline('text-generation', model='IDEA-CCNL/Wenzhong-3.5B')
+
+generator("北京位于", max_length=30, num_return_sequences=1)
+
+```
